APPARATUS FOR BEEDUCATING- AND IMPROVING HEARING.

Specification of Letters Patent.

Patented May as, 191?.

Application filed October 22, 1912. Serial No. 727,162.

To all whom it may concern:

Be it known that I, ALBERT Mannron, a citizen of the Republic of France, residing at 256 Boulevard Saint-Germain, Paris, in the Republic of France, doctor, have invented certain new and useful Improvements in Apparatuses for Reeducating and Tmprovin Hearing, of which the following is a speci cation.

This invention has for its object to pr0- vide an apparatus for reeducating and improving hearing in the case of persons dull of hearing. As is well known dullness of hearing can be cured or at least improved by subjecting the auditive organs to a sort of shampooing by the action of rationally graduated sonorous vibrations.

The apparatus according to this invention constitutes a means whereby to easily produce, regulate and use such sonorous vibrations for shampooing purposes.

Such apparatus comprises essentially a telephone receiver connected by a flexible conductor with a circuit comprising a battery or other source of electricity and a switch of quick frequence readily regulated, so that the operator, by modifying the frequence of the interruptions, can raise or lower at will the pitch of the sounds produced in the receiver.

By way of example, the accompanying drawings show one embodiment of this in vention.

Figure 1 is a diagrammatic view of the apparatus as a whole;

Fig. 2 is a plan of the vibrating blade; and

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2.

1 designates a battery or other source of electricity the poles of which are connected with a circuit 2, 3, 4, which comprises an electro-magnet 5, a buzzer blade 6 and a contact screw 7, such members being ar ranged as they usually are in the greater number of buzzer, ringing and other coils; 8 designates a telephone receiver which is branched in shunt by a flexible conductor 9 either on the coil or on the buzzer (shown in dotted lines at 9). The vibrations produced in the receiver will be more or less quick according to the quicker or slower action of the buzzer 6, so that all that need be done is to regulate the oscillations of the blade to produce in the telephone a sound of greater or less pitch.

The vibrations of the buzzer blade 6 can be regulated not only by means of the contact screw 7 in the usual manner, but also by means of an abutment screw 13 which is located between the support 11 of the said blade and the contact screw 7, at the opposite side of the latter with respect to the blade, so that both the frequence and the in tensity of the sounds produced in the re ceiver can be regulatedindependently.

Moreover, the amplitude of the vibrations in the telephone receiver 8 can be regulated either by means of a rheostat 141 located in the circuit, or in modifying the space be tween the vibrating plate 15 and the electromagnet 16, or again by interfering more or less with the vibratory movement of the abutment screw 17, which is preferably provided with a buffer 18 of rubber or other soft matter.

The vibrations of the blade 6 may also be regulated by causing the support 10 of the screw 7 to revolve or turn in such a manner that the contact takes place at a variable distance from the support 11 of the blade, or by varying the length of the vibrating part of the blade by means of a non-vibrating guide, riding on the blade and which can be brought nearer to or farther from the support 11, or again by moving the center of gravity of the blade by means of a runner secured at a variable point of the said blade, and swinging with the latter.

19 designates the slidable runner on the vibrating blade 6 and adapted to be secured at difi'erent positions by means of the set screw 20.

Claims:

1. An apparatus for improving hearing comprising an electric-circuit, a battery and a quick switch inserted in such circuit, a bycircuit mounted in shunt in regard to such switch, a rheostat and a telephone receiver inserted in such shunt circuit, such receiver comprising a casing, an electro-magnet, a vibrating membrane on the aperture of such casing, a screw traversing the bottom of the said casing, and a pad of soft material on the inner end of such screw, such pad being arranged to stop such membrane on the latter being attracted toward the electromagnet.

2. In an apparatus for increasing the hearing, a receiver comprising a casing having an opening therein, an electromagnet and a membrane vibrating over said as my invention I have signed my name in openlng, a screw passing through the botpresence of two subscribing Witnesses. tom of the oaslng, and a pad of soft material on the end of said screw and arranged ALBERT MAURICE to stop said membrane when the membrane Witnesses: is attracted toward the electro-magnet.
